Downloading the examples

I tried downloading the examples for this book.
The zip file comes down ~13mb but the files are all 0 k in length when you expand
the archive. Not much use.

4th line of code listing

4th line of code is missing in the book, causing errors upon execution. However,
the line is included in the example download on the Web site.

<%@ page import="java.util.Arrays" %>

ant invocation

The default task in the build.xml is "main", therefore running the ant command,
should only execute that task, and not the "deploy" task as shown on p.17.

last paragraph

The sentence "The application count gets reset each time the servlet is reloaded,..."
shoud read "The session count...". Also, in the same paragraph, "..., the session
state.." should read "..., the application state..." since application state is
maintained until the server itself is restarted; the session data will be wiped out
when the application is hot/re-deployed.

paragraph "How do I do that"

the URL http://localhost:8080/quote/quote
does not work, (resulting error message "the requested resource is not available")

The URL that works however looks like
http://localhost:8080/quote

This last URL seems to open the page correctly

Book says JBoss creates directory ending with quote.war. Infact JBoss creates the
directory name ending with quote-exp.war.

Chapter 2 p26

The section that describes how to run the application points to the URL as http://localhost:8080/quote/quote. However this requires a context root for the web application set in the jboss-web.xml file as /quote. The sample code that is available for download contains a context root of "/". Therefore the URL given in the book will not work out of the box with the sample. Either we have to edit jboss-web.xml file to include the new context root or try the URL as http://localhost:8080/quote
